tentuan hasil akhir dari 5x + Y = 10 14X + 3Y = 18

SPLDV

5x + y = 10
14x + 3y = 18

Jawab :
Eliminasi

5x + y = 10.....×3
14 + 3y = 18....×1

15x + 3y = 30
14x + 3y = 18
--------------------- (-)
x = 12

Substitusi

5x + y = 10
5(12) + y = 10
60 + y = 10
y = 10 - 60
y = -50

HP = {y , x = 12 , -50}

Semoga membantu ;
